GEAR- CASE.

Specification of Letters Patent.

Application filed April 16, 1909.

Patented Sept. 28, 190%). Serial No. 490,267.

To all whom it may concern:

Be it known that I, GEORGE 1V. BANDY, a citizen of the United States ofAmerica, residing at Tallahassee, in the county of Leon and btate ofFlorida, have invented certain new and useful Improvements inGear-Cases, of which the following is a specification, reference beinghad therein to the accom panying drawing.

This invention relates to gear cases, particularly adapted for use inconnection with platen printing presses and the object thereof is toprovide a gear case in a manner as hereinafter set forth which is soarranged in connection with the gear as to prevent the paper which is tobe printed or has been printed from contacting with the gears of thepress whereby soiling of the paper is obviated; to prevent foreignmatter from engaging the teeth of the gears so as to retard theoperation of the press, and furthermore to 'overcome any liability ofaccident to the press feeder from contact with during the feeding of thepress.

Further objects of the invention are to provide a gear case for thepurpose set forth which shall be simple in its construction, strong,durable, efficient in its use, readily po sitioned in operative relationwith respect to the gears, and inexpensive to manufacture.

the gears 'ith the foregoing and other objects in I view the inventionconsists of the novel construction, combination and arrangement of partshereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown the preferred emb0diment of theinvention, but it is to be understood that changes, variations andmodifications can be resorted to which come within the scope of theclaim hereunto appended.

In the drawings, wherein like reference characters denote correspondingparts throughout the several views: Figure 1 is a side elevation of agear case in accordance with this invention showing the adaptationthereof with the gears of a printing press.- Fig. 2 is a like Viewlooking from the other side. Fig. 3 is a section on line 33, Fig. 1,and, Fig. 4 is a section 011 line l4, Fig. 2.

Referring to the drawings in detail, the case consists of twosemi-circular sections 1, 2, each having a semi-circular ofl-set, theoff-sets are indicated by the reference characters 1 2 The section 1 isformed with an inwardly extending semi-circular flange 1 which opposes asemi-circular flange 2 extending inwardly and formed on the sec tion Theflanges l" and 2 abut. The olfset 1 as well as the off-set 2 beingflanged as at 2. The sections 1 and 2 are hinged together as at 5, themeans to constitute the hinge is carried by the off-sets 1 2 Thesections 1 and 2 are detachably connected together by the latch 6. Theflanges 1", 2 2 are formed at one side of the case and are relativelynarrow, the other side of the sections 1, 2, being formed with theinwardly extending flanges 2 2 which abut as at 3 and each is cut-awayas at 5 to provide a clearance. The flanges 2 are wider than either ofthe flanges 1 2 The flanges 1 2 and 2 constitute means for inclosing thegear wheel 3 which is mounted on the shaft 4 and meshes with the drivepinion 5 carried by the shaft 6 as at 7. The drive pinion 5 ispositioned within the off-sets 1 2 The gear case is fixedly secured inposition after it has been mounted to inclose the gear 3 and pinion 5and for this purpose the paper support 7 of the press is provided withan upright 8 and the upper portion of the case is fixedly secured to theupright 8 by the clamp 9. The lower portion of the case is fixed to themachine frame through the medium of the adjustable clamps 10 and 11. Theclamping of the case to the machine frame is had after the case has beenpositioned to inclose the gear 3 and pinion 5. To provide for thestraddling of the shaft .t the clearance hereinbefore referred to isutilized.

When the case is set up in operative relation with respect to the gear 3and pinion 5 the teeth of the pinion and also the gear are protected notonly at the edge but also the sides and owing to the employment of thecase in the manner as shown, the paper which is being printed or hasbeen printed is prevented from contacting with the gear or pinion so asto overcome any liability of the paper becoming soiled and furthermoreforeign bodies are prevented from interfering with the operation of thegear as well as the pinion and furthermore the case prevents anylikelihood of the attendant being injured by the gear during the feedingof the press.

lVhat I claim is:

A gear case comprising two sections, each of saidsections being formedwith a semicircular off-set, means at one end of each of the off-setportions for hinging the sections together, means fordetachably-connecting the tree ends of the sections together, said meansbeing diametrically-opposed to said hinge, each of said sections andeach ot'f-set being provided on one side with an inwardlyextendingSGHIl-Cll'CUlfll flange, the flanges ot' the off-sets being formedintegral with the flanges of said sections, the flanges of the off-setsabutting and the flanges of the sections abutting ateach end saidsections being adapted to inclose a gear Wheel and the off-set portionsbeing adapted to inclose a pinion, each of said sections furthermorebeing provided on its other side With an inj wardly-extending flange ofgreater Width than the'flange on its opposite side and abutting at oneend, a pair of clamps carried by one of the sections and a clamp carriedby the other of the sections, said clamps fixedly securing the case inposition and for maintaining the case in operative relation with respectto the gear and pinion.

In testimony whereof I aflix my signature in the presence of twoWitnesses.

GEORGE I. RANDY. Vitnesses JOHN Gnmvoo COLLINS, T. J. APPLEYARD.
